Description of inventions (8) Multiple enzymes, such as: Glycerol ester and pentaerythritol of wood rosin_, Glycerol ester of hydrogenated rosin, glyceride and pentaerythritol are particularly suitable. The resins that can be hydrogenated are hydrocarbon resin, ketone resin, polybromoamine resin, rosin , Coumarone resin, straw resin, chlorinated aliphatic or radonized aromatic hydrocarbon resin. Examples of hydrocarbon resins are coke oven gas, cracked naphtha, gas oil (g a s 〇 i 1) and straw oil. The preferred S resin is hydrogenated petroleum resin. These are usually prepared by catalytic hydrogenation and thermal polymerization to crack the steam of the steamed portion of petroleum. It is also possible to produce hydrogenated resins by polymerization of unsaturated hydrocarbons through catalysts. Commercially available hydrogenated hydrocarbon resins suitable for use in the present invention are those sold by Hercules Corporation, REGALREZ and REGALITE. The preferred saturated alicyclic resin used in the present invention is obtained by hydrogenating an aromatic hydrocarbon resin. The aromatic resin itself is obtained by polymerizing reactive unsaturated hydrocarbons. This reactive unsaturated hydrocarbon contains an aromatic hydrocarbon in which the reactive double bond is generally present in the two as the main component. The alicyclic tree wax is obtained by hydrogenating the aromatic resin to all, or almost all of the unsaturation (including the double arsenic in the aromatic ring) disappears. Although the aromatic hydrocarbons useful in the preparation of the fat-oil resin are mainly compounds containing a reactive double bond on the side, the aromatic hydrocarbon may also include aromatic smoke having a reactive double bond in the fused ring. Examples of such useful aromatic smokes include vinyl meth, vinyl xylene, propylene benzene, styrene, p-toluene, indene, methyl indene, and ethyl indene. Mixtures of several of these smokes can be used. The very convenient industrial source of these aromatic welds is the residues obtained by steaming and removing the useful olefins (such as ethylene anti-propylene) from the thermal cracking products of the heavy petroleum part.

Description of the invention (9) The boiling point of the residue is 20 ° to 3 0 0 C, preferably 140 ° to 3 0 0 C. The polymerization of the reactive hydrocarbons can be carried out in the presence of a polymerization catalyst such as sulfonic acid, phosphoric acid, or amphoteric gold hydride. The resulting aromatic hydrocarbon resin is hydrogenated until the cell and bond (including the double bond in the aromatic ring) are substantially completely saturated. Generally hydrogenation is carried out in the presence of a large amount of highly active catalysts such as Lei iSuaney) nickel palladium under high temperature and at least 150kg / cb2 of hydrogen® force. Grate formation of aromatic double bonds can be determined by comparing the infrared medium or ultraviolet absorption spectrum of the resin before kryptonization and after hydrogenation. The 700CB-1 and 750c · -1 of the aromatic ring in the infrared spectrum, and 261.5bU and 274.5au in the ultraviolet medium spectrum have ultra-excited absorption. This absorption decreases when the aromatic ring is hydrogenated into an alicyclic ring, and when all the rings When they are saturated, they disappear. Those who desire to obtain a hydrogenation of at least 80 ° C and preferably at least 90 ° C measured by the disappearance of the number of extra shocks. The alicyclic resin used in the present invention has an M-ball and a ring method with a cooking point of 85 ° to 140 °, preferably 100 t to 140 °.

As shown, when the percentage of modifier is increased from 0〆 to 20〆, the layer shape of Examples Ai 2 and 3 (both represent the prior art e) basically maintains a straight line. 0 Round shape 1 generally exhibits a negative slope I This means that when the modifier is added to the resin, the transmission of water vapor is reduced. In order to obtain a large moisture barrier, it is necessary to add more than 20 〆 1 1 of modified m to the resin. However, as described above »The resin containing the modified ft of large ft 1: | often has reduced dimensional stability and can be processed And operability 0 1 The circles of Examples 5, 8 and 12 illustrate the unexpected hospitality presented by the HCPP resin / modified m-doped 1 I and XI of the present invention.

Description of invention (24) Added to HCPP resin For example, when it is close to 8, the slope of the circle is flattened to substantially zero, indicating that there is no further reduction in VVTR. On the other hand, the blending compound of the present invention is modified with a relatively low amount_, that is Up to 8 weight 〆 and preferably 3 to 6 weight 〆 modifiers to the minimum WVTR. As a result, a polypropylene-based film that exhibits a substantially maximum moisture barrier can be formed without loss of dimensional stability and processability Performance and operability 0 As described in Example 14, the film structure of the present invention also exhibits unexpectedly increased MD and TD numbers compared to the film structure with a conventional OPP-based core layer. Obviously, this Wait for the increase in the number of MD and TD For low setting (please read the precautions on the back and then fill in this page) r The negative surface of the sound pretends to be indefinitely clear, and the case is as complicated as the case.
